If Gwen Stefani's having kids past 40, it must be cool. According to a report from In Touch Weekly, the 43-year-old singer and her husband, Gavin Rossdale, are expecting their third child. "She's just trying to focus on resting right now. She wants to make sure that all is well with the baby," a source told the gossip magazine. The couple already have two sons, Kingston and Zuma, and Stefani told Marie Claire they previously tried to have another baby in 2010.
